Okay Set Harth, do you agree with this statement
"Midi-Chlorians are what made life possible and midi-chlorians are what allowed the Jedi (and the Sith) to understand the ways of the force." This is basically paraphrasing Qui-Gon.
So then, midi-chlorians are supposed to exist in all living things. Since midi-chlorians are ever present, it can be argued that everyone is Force sensitive, its just a matter of different intensity.
With me so far??
Okay, fast forward to OT, with Luke on the Falcon, being trained, and Han Solo says "That Force thing is non-sense." Well, why? There is a very scientific explanation to Force Sensitivity. Everybody has Midi-Chlorians, so why wouldn't Obi-Wan simply explained it pointed out that Han also has Midi-Chlorians and if only he had received training, he would also know the will of the Force?
You see, in the OT, the Force was illusive and the knowledge of it is not meant for everyone. But PT told us there is a "silver bullet" that everyone can look at for proof that the Force does exist. That is a drastic difference.
